Does NOT FIT HD models (NV4500), 2005+ models (Getrag 238), Dakota, or any other model; NOT for custom use

Base configured for shifter cup receptacle height of 1/4" as original to these models

IF your transmission has been serviced, it MAY REQUIRE A DIFFERENT BASE. If you install the wrong one it will not work properly and could cause damage. To confirm height, remove shifter base and measure transmission as shown in last pic
